阿克苏地区土地资源开发利用与生态环境的耦合关系分析

Analyzing the Coupling Relationship between Aksu Region Land Resources Development and Ecological Environment

良性的协调关系有利于促进土地资源的永续利用和生态环境质量的改善及自我恢复的重建能力,过度的开发利用土地资源只会加剧生态环境的脆弱性,进一步制约土地的可持续开发利用。本文从阿克苏地区的基本现状出发,运用耦合评价模型和主成分分析法,研究两者耦合关系的程度及影响机理,分析土地开发利用与生态环境在2000～2010年间的动态演变过程。研究结果表明:(1)阿克苏地区土地开发利用强度不断增大,生态环境状况整体处于波动状态,但近两年环境有所改善,两者的协调发展仍然面临巨大压力。(2)土地开发利用与生态环境的动态演变关系不满足长期的均衡关系,耦合程度在波动中逐渐减弱,生态环境的良性状况呈现不明显。本文认为:坚持土地开发利用与生态环境改善同步进行,维系生态环境相对稳定的运行机制,才能保持区域经济可持续发展。

Benignly coordinating relations to promote land sustainable use of resources and the ecological environment quality improve- ment and self recovery reconstruction ability, excessive exploitation and utilization of the land resources will only aggravate the ecologi- cal environment vulnerability; further restrict the sustainable development and utilization of the land. This article, from the basic cur- rent situation of Aksu area, by using the coupling evaluation model and principal component analysis, the study both the degree of cou- pling relationship and the influence mechanism, analysis the development and utilization of land and ecological environment in 2000 ~ 2010, the dynamic evolution process. The results of the study show that： （1） the Aksu region development of land use intensity in- creasing, the ecological environment condition overall fluctuations, but nearly two years environment has been improved, both the coor- dinated development is still faced with great pressure. （2） the development of land use and ecological environment of the dynamic evo- lution relationship does not meet the long - term equilibrium relationship, coupling degree in fluctuation in weakened gradually, the ec- ological environment of the benign conditions present is not obvious. This paper holds that ： adhere to the development of land use and ecological environment improvement synchronously, sustain ecological environment relatively stable operation mechanism, to maintain the sustainable development of regional economy.
